Abstract: The present invention has an object to provide a compact quadrature modulator manufactured at low cost in such a manner that an input level is low over a wide high frequency band, and few input signals are wrapped around an output terminal.  The quadrature modulator is mainly constructed of a multi-layer substrate into which a 90-degree phase shifter is assembled, a semiconductor integrated modulator circuit into which two sets of 2-phase modulators and an output signal in-phase synthesizing circuit, and a lid.  The multi-layer substrate is constructed of "n" pieces of layers in total, namely from a first substrate corresponding to an uppermost layer to an n-th substrate corresponding to a lowermost layer.  The first substrate layer is a layer for assembling a semiconductor integrated circuit, or a layer for connecting a substrate with a semiconductor integrated circuit.  The 90-degree phase shifter is constituted by distributed coupling circuits having wavelengths of .lambda.g/4 by both of wiring patterns formed on the substrates corresponding to an intermediate layer of the multi-layer substrate.  A wiring pattern connected to a ground terminal and other circuit components are formed on the n-th substrate layer, i.e., the lowermost layer.

Abstract: There is provided a mobile radio communication device which is designed to prevent dishonest applica-tions by using a management table (30) for storing a plurality of MINs and count values as authentication parameters corresponding to the MINs and effecting the authentication procedure at the time of radio connec-tion to a base station.  Whether or not an input MIN is already set in the management table (30) is determined at the time of MIN setting operation, and if it is already set, it is determined that the setting operation is a resetting operation and the already set MIN and count value are kept held as they are.  On the other hand, if the input MIN is not set in the management table (30), whether or not a MIN having a count value of "0" is set in the management table (30) is determined, and if it is set, an input MIN is set in place of the above MIN, and if it is not set, an input MIN and the initial value "0" of the count value are set in an available area of the management table (30).

Abstract: A novel coulter, as well as a novel tillage tool including that novel coulter, are provided herein. The coulter includes a circular body having a peripheral edge, a centre portion, and a radius. A plurality of waves are formed in the body, each wave including a curved crest and an adjacent curved valley defining a wave width at the peripheral edge which is disposed perpendicular to the plane of the circular body. Each crest and adjacent valley extend back from the peripheral edge in respective adjacent lines which are disposed at a predetermined acute angle with respect to the radius. The coulter is rotatably attachable to an implement frame at a centre portion such that a leading peripheral edge of the coulter rotates in a downward direction as it enters soil, thereby positioning the lines of each crest and valley to enter the soil at a nearly vertical orientation, whereby compaction of the soil is minimized. The tillage tool includes an implement frame for movement in a direction of travel over soil to be tilled.  The tillage tool is provided with the above-identified soil-engaging coulter which is operably attached to the frame and is positioned forward of a no-till implement which is also operably attached to the frame.
